Is this the most important century in human history? Businesses, governments, and consumers are increasingly realizing the severity and scale of the climate crisis. Companies around the world are starting to take action by reducing their own emissions and by purchasing carbon credits to offset their unavoidable emissions. The suppliers of these carbon credits, project developers, are struggling to keep up with demand and face colossal scaling challenges. Experts estimate that the global supply of carbon credits will have to increase by 4,000% in order to meet annual demand in the coming years. Most suppliers, however, lack the resources and tools required to efficiently manage their projects at scale. About BlueLayer BlueLayer’s mission is to reverse climate change by developing the software stack that will enable developers of carbon credits to bring quality supply to market. We are empowering with software tools thousands of companies producing carbon credits, in order to automate their inventory and other core operations.
